Letters Patent No. 100,096, datedfFebmary 22, 1870,

`1MPRovEME1vT IN LCANIZED RUBBER HOSE.

lThe "Sehedule referred to in these Letters Patent and making part of the same.

To' all whom it may concern: yBe it known that I, HENRY A. ALBEN, of Matteawan,in the county of Dutchess, and vState of New York, have invented certain new and useful Improvements in Vnlcanzed India-Rubber Hose; and I do hereby declare thel following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, in which- Figure l is a side elevation of a portion of hose made in accordance with my invention.

Figure 2 is a longitudinal central section of the same.

Figures 3 and 4 are like views of a modied faim of the hose. y

My invention relates to vulcanized rubber hose, the bodyof which is composed of alternate plies of canvas and layers of India rubber, formed into the required shape upon a mandrel, and then vulcanized in the mannerwell known to those skilled in the art to which this invention pertains.

Usually, it is the practice to wind the plies, either spirally or otherwise, so that the canvas shall be in 'continuous sheets or layers, this being considered neoessary in-order to obtain hose of the requisite strength.

I have, however, in the manufacture of such hose, discovered by continued and carefnlzexperimentthat more canvas is consumed than is necessary, and that one or more of the plies or layers of canvas may be reduced, without detracting from the strength of the hose.

For instance, in hose having three plies of canvas, as represented in the drawings, I lessen the quantity of canvas ordinarily employed .in'its manufacture by making the inner two plies in J. he usual way, and then employing, in lieu of th'e outer continuous ply, a band or ribbon of canvas,wound either spirally, as shown at a, or arranged in rings, as seen at b, there being aconsiderahle spacebctween the folds of the spiral or the The space between the rings b or lthe folds lof the l spiral a can be greater or lesser than shown in the drawing, this being discretionary with the in anufactlner;` and this arrangement is not limited to the outer ply, for a'ny one of the layers of canvas may be. thus formed; and further, two or more of the ca uvasflayn ers can be arranged as described, this beingdet-ermined by the size of the hosethe number of plies entering into its composition, and the use 'for which it is designed.

If two spirals are used, they should be wound or coiled iu opposite directions, so as to cross each other.

in the manner of latticework, so as to leave diamond'- shaped` spaces between the spirals. t, 'lhe canvas band or ribbon may be arranged spirally or in rings, or wound in any other equivalent manner.l

Having describedv my invention, and the manner in which the same is or may he carried into effect,

What I claim, and desire to secure by Let-ters Patent, is, r

As a new manufacture, hose composed of vulcanized India rubber and canvas, or equivalent material, as

described, having one or more of the canvas 'plies
